Hi Haunted!!! The SQR has a very nice draw, its not room filling , but dense and full.
I like it better than the X but thats because of my hands. The X has the top fill and the locking feature.
Top fill is nice, but like most , top fills a tiny bit always seems to ooze out from screwing section back on.
The locking is a nice but not necessary feature, at least to me. I guess if you travel a lot and go
through a lot of temp fluctuations in your daily routine , it would be an added plus. This was hard on my hands. The X has a LOT more air, but can be dialed back, but found the R to taste better.
Its a warm
vape but not as hot as I found the Prom and Achilles to be.
